Magnetic flow switching type axial magnetic field magnetoelectric machine with middle stator structure

Abstract

The invention relates to a magnetic flow switching type axial magnetic field magnetoelectric machine with a middle stator structure, which is a double-air gap magnetoelectric machine consisting of a stator (1) and two rotors (2). The stator (1) and the rotors (2) are coaxially arranged; the stator (1) is clamped between the two rotors (2); air gaps with a certain thickness are reserved between the rotors (2) and the stator (1); and each stator (1) consists of 12 H-shaped stator iron cores (5), 12 permanent magnets (6) and 12 coils (7), wherein the H-shaped stator iron cores (5) and the permanent magnets (6) are alternately placed to form a disk; the H-shaped stator iron cores (5) and the permanent magnets (6) on the stator (1) correspond to each other, but the permanent magnets in the stator alternately charge magnetism along the circumferential direction; the permanent magnets and concentrated armature windings are all arranged on the stator; and neither permanent magnets nor armature windings are arranged on the rotors. The simple rotor structure can effectively improve the running reliability of the magnetoelectric machine; the axial magnetic field structure enables the axial dimension of the magnetic field to be shortened, and thereby the magnetoelectric machine has higher power density; and an outer rotor structure enables the rotor to play a fan role when the rotor rotates.

Description

technical field [0001] The invention relates to an axial field permanent magnet motor with an intermediate stator structure and flux switching type, which is an improvement to the traditional intermediate stator structure axial field permanent magnet motor and belongs to the technical field of permanent magnet motors. Background technique [0002] my country is rich in rare earth resources. The reserves of rare earth ores are about four times that of other countries in the world. The output of rare earth ores and rare earth permanent magnets ranks among the top in the world. The scientific research level of rare earth permanent magnet materials and rare earth permanent magnet motors has also reached the international advanced level. Therefore, it has important theoretical significance and engineering practical value to give full play to the advantages of my country's rich rare earth resources and vigorously research and promote the application of various permanent magnet mot...
